No, not a full history, just a tag history.

I'm not sure, is it?  Is there scripts already out there to overcome
the problems suggested?  If there are, I would sure appreciate knowing
about them. :)

That's true, and I suppose that's not quite as good as what exists
right now.  But does gentoo really have less than 24 hour bug fix turn
arounds?
